Abstract:
Are you responsible for a DNS domain, perhaps professionally, or a "vanity" domain for your personal email? Have you given much thought to the DNS resolvers for that domain? Every domain requires at least one DNS server, and everyone has probably heard that they should have a geographically disparate secondary server to hedge against catastrophic outages (network, building, etc). Assuming you don’t have the luxury of a globally distributed set of datacenters, where should your secondary DNS server be hosted? This talk will present one man's quest to answer that question, along with the data used to visualize and understand the available options. There will also be a brief discussion of how that data was collected, and open source code (in Go, http://golang.org) to do it yourself.

Bio:
Aaron S. Joyner is a Sr. Systems Engineer in the Site Reliability Engineering (SRE) group at Google. He has been working as a SysAdmin for more than 15 years at companies such as Global Knowledge, Intrex.net, and MWG Biotech. When living in Raleigh, he was actively involved with the Triangle Linux Users Group, serving on the steering committee as SysAdmin in 2004-2005, and giving talks on DNS for NC*SA and TriLUG. Since joining Google in 2005, he has helped to maintain their internal DNS infrastructure and been primarily responsible for designing, implementing, and supporting Google's serial console systems. For the past ~4 years, he has been leading a team of SREs responsible for supporting production authentication and machine management systems.

Michael Tiemann started the world's first open source software company, thereby placing the topic of open source into the field of economics.

Ignored for several years, open source has helped to rewrite the rules of economics, and has become an important subject among Nobel laureates. After reviewing 20+ years of Nobel Prize lectures in economics, Tiemann has synthesized a new perspective on the economics of cloud computing and the continued role that open source will play in the development of this new paradigm.

Keith will talk about intellectual property as a reality that shapes the context for open source software, particularly when overlaid against trends in technologies such as mobile and cloud computing, provide the history of Open Invention Network and its licensee community, and discuss Linux Defenders and other opportunities for community members to contribute proactively for the benefit of open source software.

Keith Bergelt is the chief executive officer of Open Invention Network® (OIN), the collaborative enterprise that enables innovation in open source and an increasingly vibrant ecosystem around Linux. In this capacity he is directly responsible for enabling, influencing and defending the integrity of the Linux ecosystem. Central to the achievement of his goals is the acquisition and transfer of patent rights designed to permit members of the Linux ecosystem to operate free of the threat of assertion and litigation from those whose business models are antithetical to innovation and global economic growth in information technology and computing.

Department of Electrical and Computer Engineering, NC State Engineering Building II Room 1021, Centennial Campus (just across the street from Red Hat)Parking: The parking decks are free after 5pm, and street parking on Oval Drive.Map:Google MapsVideo:YouTubeRSVP:EventBrite (You don't actually need to bring a ticket to attend. Getting one just helps us prepare for refreshments so nobody goes without pizza!)

We'll be putting the July meeting in the hands of the TriLUG community by holding a series of Lightning Talks. Lightning talks are short talks of about 5-15 minutes long that give the audience a taste of a topic rather than going into the great detail associated with formal presentations. If you've been working on a cool project lately or learned something cool about technology, you are qualified to present something!

If you have an idea for a talk, please pitch it on the TriLUG mailing list and the community will help you cultivate it into a presentation you can be proud of. Prepend your subject line with "LT:" to make it easy to find (ie subject = "LT: Using Inkscape"). The Steering Committee will then collate a list of the topics and speakers from the mailing list posts. There isn't a set theme yet, but we expect a theme will emerge from the discussions in the next couple of weeks.

We are extremely fortunate to have Cathy Davidson speaking June 13th at TriLUG! Make sure you do not miss this rare opportunity! Cathy Davidson is an extraordinary individual and a brilliant minded speaker, who is a highly influential player in the world of open education in the universities.
She is the first educator to serve on the six-person Board of Directors of the Mozilla Foundation! She'll include in her talk, discussion of her two current peer-taught, peer-evaluated classes and her upcoming work to prepare for a Coursera MOOC entitled "The History and Future of Higher Education". Make sure your schedule allows for you to attend this special event. Also, spread the word to your fellow digerati and invite them to attend.

Please note that this meeting will be held at a new venue, so there will be some shifts in the usual schedule. NCSU does not permit food in its classrooms, so we are going to begin the meeting with a reception/networking over our usual pizza in the atrium of Engineering Building 2. At about 7:30 we'll move to 1021 to begin businesss, community announcements, and the presentation.
